is it easier than rotating pots? it's just spreading light out, so as long as the average isn't too low, it'll be fine. drop below 22 dli for an area and might not form very good buds.. and 22 would be lower side of yield too, consider 35-40 dli for ambient co2 is a good guesstimate for max yield.
it won't stress them. plants bend toward the sun throughout day. normal behaviour, relatively speaking.
